ABB SPAM 150 C Replacement – REX615 Retrofit

ABB SPAM 150 C is a legacy motor protection relay used in older motor control panels, switchgear and industrial plants. ABB lists the relay as not active since 2016, so most enquiries today are for replacement of an installed SPAM 150 C, maintenance spares, shutdown requirements or modernisation of an existing motor protection panel.

ABB officially includes SPAM 150 C in its SPACOM-to-REX615 Relay Retrofit Program.

Both SPAM 150 C trip-contact versions are covered:

• SPAM 150 C with normally open trip contact
• SPAM 150 C with normally closed trip contact

ABB provides separate retrofit order codes for the NO and NC versions, so the existing relay version should be checked before a replacement is finalised.

For an ABB SPAM 150 C replacement or REX615 retrofit enquiry, please send:

• Complete ABB SPAM 150 C order code
• Clear photograph of the relay nameplate
• Normally open or normally closed trip version
• CT secondary – 1 A or 5 A
• Auxiliary supply voltage
• Existing protection settings, if available
• Motor rating
• Required quantity
• Destination country

ARP IMPEX supplies and exports legacy ABB relay requirements and handles enquiries for ABB SPAM 150 C replacement relays, motor protection relay spares and SPAM 150 C to REX615 retrofit requirements.

Description

ARP IMPEX is a supplier and exporter of ABB SPAM 150 C motor protection relays for existing motor control panels, industrial switchgear, plant maintenance and replacement requirements.

SPAM 150 C is a current-measuring multifunction motor protection relay from ABB’s older SPACOM range. It was mainly used for the protection of medium and large three-phase AC motors controlled by contactors or circuit breakers.

The relay continuously measures the three motor phase currents together with neutral current. From these measurements, it supervises the thermal condition of the motor and responds to problems such as overload, excessive starting time, locked rotor, high current, earth fault, phase unbalance, incorrect phase sequence and undercurrent.

Although SPAM 150 C was developed mainly for motor protection, ABB also states that it can be applied to transformers and feeders where overcurrent, overload and non-directional earth-fault protection are required.

Today, buyers searching for this relay are generally looking for:

• ABB SPAM 150 C replacement relay
• SPAM 150 C price and availability
• Discontinued ABB motor protection relay
• Matching spare for an existing motor panel
• ABB SPACOM motor relay replacement
• Plant shutdown spare
• SPAM 150 C NO or NC version
• SPAM 150 C to REX615 retrofit

ABB SPAM 150 C Models and Versions

SPAM 150 C is one motor protection relay model rather than a large product family.

ABB supplied the relay in two main versions based on the trip-contact arrangement.

ABB SPAM 150 C – Normally Open Trip Contact

This version uses a normally open trip contact.

Applicable power supply/output modules include:

• SPTU 240R2
• SPTU 48R2

The R2 versions provide the normally open trip arrangement.

ABB’s REX615 retrofit program identifies this separately as:

• SPAM 150 C (NO)

ABB SPAM 150 C – Normally Closed Trip Contact

This version uses a normally closed trip contact.

Applicable power supply/output modules include:

• SPTU 240R3
• SPTU 48R3

The R3 versions provide the normally closed trip arrangement.

ABB’s REX615 retrofit program identifies this separately as:

• SPAM 150 C (NC)

For replacement purposes, the NO/NC version should not be assumed from the SPAM 150 C model name alone. Check the existing order code, output module or relay nameplate before quotation.

• Normally open and normally closed trip versions

ABB lists thermal overload, high-set overcurrent, phase unbalance, single-phasing, incorrect phase sequence, earth fault, undercurrent and motor start-up supervision among the main functions of SPAM 150 C.

Motor Thermal Overload Protection

One of the main functions of SPAM 150 C is thermal protection of the motor.

The relay calculates the motor’s thermal condition from the measured current and can provide a warning before the thermal trip level is reached. It can also prevent the motor from being restarted while the calculated thermal level is still too high.

For a buyer replacing an existing SPAM 150 C, the important information is usually the motor full-load current and the existing thermal settings rather than a detailed thermal-model calculation.

Motor Start and Stall Protection

SPAM 150 C supervises motor starting and can detect an abnormally long or stalled start.

The relay allows the motor-start current and maximum start duration to be set according to the motor. It also includes cumulative starting supervision to prevent repeated starts from causing excessive motor heating.

This function is particularly relevant for larger motors driving high-inertia equipment.

Applications

ABB SPAM 150 C is commonly found in:

• Medium-voltage motor protection
• Large three-phase motors
• Medium-sized industrial motors
• Circuit-breaker-controlled motors
• Contactor-controlled motors
• Pump motors
• Compressor motors
• Fan and blower motors
• Conveyor motors
• Mill motors
• Crusher motors
• Process plant drives
• Industrial motor control panels
• Motor control centres
• Power plants
• Cement plants
• Steel plants
• Mining plants
• Oil and gas facilities
• Petrochemical plants
• Water and wastewater facilities
• Existing ABB SPACOM installations
• Legacy motor protection panels
• Plant shutdown spare requirements
• SPAM 150 C replacement projects
• SPAM 150 C to REX615 retrofit projects

ABB identifies medium and large three-phase motors in conventional contactor- or circuit-breaker-controlled drives as the main SPAM 150 C application.

Other Applications

Although SPAM 150 C is primarily a motor protection relay, ABB also states that it can be used for:

• Transformer overcurrent and overload protection
• Feeder overcurrent protection
• Single-phase applications
• Two-phase applications
• Three-phase overcurrent applications
• Non-directional earth-fault protection

For these non-motor replacement requirements, the existing protection scheme should be checked before selecting a modern replacement.

ABB SPAM 150 C Replacement with REX615

ABB officially supports SPAM 150 C replacement through its SPACOM-to-REX615 Relay Retrofit Program.

ABB lists separate retrofit arrangements for:

• SPAM 150 C (NO)
• SPAM 150 C (NC)

The current ABB retrofit ordering data identifies:

• SPAM 150 C NO: RRPSPAM150OREX615C / RRPSPAM150OREX615N
• SPAM 150 C NC: RRPSPAM150CREX615C / RRPSPAM150CREX615N

The final letter identifies whether the REX615 is supplied with or without ABB pre-configuration.

ABB’s retrofit arrangement includes the REX615 relay together with a retrofit connector kit. The connectors are marked to correspond with the old SPACOM terminal numbers, helping reduce the amount of rewiring required during the changeover.

ABB’s application documentation also states that SPAM 150 C motor-protection functions can be replicated in the newer relay, although some functional differences have to be considered during engineering.

For this reason, REX615 should be described as an ABB-supported retrofit solution, not as a simple plug-in replacement requiring no engineering.

Before finalising a SPAM 150 C retrofit, check:

• Normally open or normally closed version
• CT secondary – 1 A or 5 A
• Motor rated current
• Existing thermal settings
• Motor starting current and start time
• Earth-fault settings
• Phase-unbalance settings
• Undercurrent settings
• Auxiliary supply
• Trip and alarm wiring
• External blocking/control signals
• Existing communication requirement
