Descripción del producto

Ciclo de vida:Sucesor:

The ABB SPAM 150 C Motor Protection Relay is a versatile multifunction relay designed for the comprehensive protection of a.c. motors. This relay is suitable for large or medium-sized three-phase motors in conventional contactor or circuit breaker controlled systems. It can also be used for the protection of feeders and transformers. The relay offers three-phase thermal overload protection, high-set overcurrent protection with instantaneous or definite time operation, and phase unbalance and single-phasing protection with inverse time characteristics. Additionally, it provides fast operating incorrect phase sequence protection, sensitive earth-fault protection with definite time characteristics, and undercurrent protection with definite time characteristics.

The SPAM 150 C relay includes several selectable motor start-up supervision methods and continuous self-supervision of hardware and software. It features a sophisticated self-supervision system with auto-diagnostics and an interface for extensive data exchange with substation level data acquisition and control systems over a fibre-optic bus. The relay is part of the SPACOM product family and ABB’s Distribution Automation system, ensuring compatibility and integration with existing systems.

This relay meets the requirements for ExE motor drives of Zone 1 and is CE marked according to the EC directive for EMC. It is supported by powerful soft...
