      SPAM 150 C current measuring multi-function relay

      SPAM150C

      Product Information:

      The ABB SPAM 150 C is a microprocessor-based digital current measurement multi-functional integrated protection relay. This device is primarily used for the comprehensive protection of medium to large-sized three-phase AC motors and is widely applied in various motor drive circuits controlled by traditional contactors or circuit breakers. Furthermore, due to its flexible configuration, this relay is also suitable for feeder and power transformer circuits requiring single-phase, two-phase, or three-phase overcurrent and overload protection.

      Technical notes

      The ABB SPAM150C is a comprehensive microprocessor-controlled protection relay designed specifically for medium to large-sized three-phase AC motors (including Zone 1 ExE explosion-proof motors). Based on the highly integrated SPCJ 4D34 core chip, this device comprehensively covers three-phase thermal overload protection (49) based on the thermal mirror principle, instantaneous and time-limited overcurrent protection and locked rotor protection (50/51/14), negative sequence imbalance and phase loss protection (46), zero-sequence ground fault protection (51N), and no-load undercurrent protection (37). It supports standard current transformer inputs of 1A and 5A, features self-testing and fiber optic digital communication, and can operate stably under high-voltage or low-voltage dual auxiliary power supplies. Its classic IP54 aluminum housing provides extremely stable and sensitive motor safety protection for high-risk industrial power distribution systems.

      PRODUCT & ORDER FAQS

      Questions buyers ask about SPAM150C

      • Which evidence confirms 1 A/5 A current inputs for SPAM150C?

        Use the complete SPAM150C marking and verify 1 A/5 A current inputs. A similar faceplate or shortened code is not sufficient.

      • Why must thermal prior alarm be checked before ordering SPAM150C?

        Thermal prior alarm controls whether SPAM150C matches the receiving ABB SPACOM protection relays arrangement.

      • How does ABB describe high-set overcurrent on SPAM150C?

        ABB SPAM 150 C User's Manual and Technical Description is the source boundary. It supports exact relay functions and ratings; unsupported nearby-model values are excluded.

      • What should technicians record about earth-fault stage before removal?

        Record earth-fault stage, the installed position, every connector and the pre-service operating state before disturbing SPAM150C.

      • Where does phase unbalance affect the application of SPAM150C?

        Phase unbalance matters because protects circuit-breaker- or contactor-controlled AC motors and can be configured for feeder duties. Confirm the system drawing and the complete article identity.

      • How is phase sequence tested after SPAM150C is installed?

        After fitting SPAM150C, check phase sequence and then secondary-injection test every enabled stage, trip path, alarm and restart inhibit.

      • Which source governs undercurrent stage for SPAM150C?

        Cross-check undercurrent stage against ABB SPAM 150 C User's Manual and Technical Description and the actual unit marking; do not import specifications from a nearby model.

      • What must the quotation state about SPA serial bus for SPAM150C?

        The quotation for SPAM150C must state the supplied condition, included items, packing data, dispatch point, origin evidence and destination customs treatment.
