Specifications
The ABB SPAM150C is a current-measuring, multifunction Motor Protection Relay from the ABB SPACOM Series. It is designed for comprehensive protection of medium- and large-sized three-phase AC motors controlled by circuit breakers or contactors. The relay continuously measures the three phase currents and residual current, calculates the motor’s thermal condition, supervises starting and running conditions, and initiates alarms, tripping, or restart inhibition when an electrical fault or unsafe operating condition is detected. It can also protect feeders, transformers, resistive loads, and other equipment requiring overload, overcurrent, or nondirectional earth-fault protection.
Rated phase-current input 1 A or 5 A
Phase-current measuring range 0–63 × In
Continuous current withstand 4 A for the 1 A input
or 20 A for the 5 A input
One-second current withstand 100 A for the 1 A input
or 500 A for the 5 A input
Dynamic half-wave current withstand 250 A for the 1 A input
or 1,250 A for the 5 A input
Input impedance Less than 100 mΩ at 1 A
or less than 20 mΩ at 5 A
External control-input voltage 18–265 V DC or
80–265 V AC
External control-input current 2–20 mA
Output-contact rated voltage 250 V AC/DC
Continuous output-contact current 5 A
Application Industry
01
ExE Motor Installations Supports thermal protection of Ex motors in potentially explosive atmospheres. The relay itself must be installed outside the hazardous area, with an ambient operating range of −10°C to +55°C.
02
Resistive Elements and Other Non-Rotating Loads Can be configured as a multifunction protection relay when thermal and current-based protection is required.
03
Medium- and Large-Sized Three-Phase AC Motors Provides comprehensive electrical protection for conventional industrial motors controlled by circuit breakers or contactors.
04
Multiple Large Motors on Weak Electrical Networks Its cumulative start counter and restart-inhibit functions can prevent simultaneous or excessively frequent motor starts.
FAQ
What motor applications is the ABB SPAM150C designed to protect?
It is designed primarily for comprehensive protection of medium- and large-sized three-phase AC motors controlled by circuit breakers or contactors.
Which current-transformer secondary ratings can the relay accept?
The ABB SPAM150C provides rated phase-current inputs of 1 A or 5 A, allowing it to match common protection current-transformer secondary ratings.
Which motor faults and unsafe conditions can the ABB SPAM150C detect?
It provides functions for thermal overload, start-up and stall supervision, high-set overcurrent, earth fault, phase unbalance, single phasing, incorrect phase sequence, undercurrent, and restart inhibition.
Which auxiliary-supply version should a buyer select?
The ordered relay must match the installation supply: available versions support either 80–265 V AC/DC or 18–80 V DC. Buyers should also confirm the required normally open or normally closed trip-contact configuration.
Can Moore Automation confirm the exact ABB SPAM150C version before purchase?
Yes. Provide the complete relay order code, auxiliary-supply voltage, system frequency, and required trip-contact arrangement so the sales team can check configuration, availability, pricing, and technical documentation before quotation.
