Technical Parameters Parameter Category Specification Notes Base Device GSH202 200A frame high-performance contactor. Variant/Accessory Code B25 This suffix is critical but its meaning is not generic. In ABB's GSH coding: • B likely indicates a specific "Basic" version or a version without a front-mounted rotary handle (like -Cxx codes have). It may imply a flush-mounted design intended for operation only via its electrical coil. • 25 is likely a performance or accessory package code. It could indicate a standard set of included items, such as: - A specific number of built-in auxiliary contacts (e.g., 1NO+1NC). - Undervoltage release (MN) or Shunt Trip (MX) pre-installed. - Specific terminal type or connection style. Rated Operational Current (Ie) 200 A (at AC-3, 400V) Standard rating for the GSH202 frame. Rated Operational Voltage (Ue) Up to 690 V AC Control Coil NOT SPECIFIED. The B25 code does not define the coil. This is a major point of ambiguity. The contactor requires a coil, typically specified as a separate part of the order code (e.g., GSH202 A230 B25 for a 230V AC coil). Must be verified on the device nameplate or in the complete ordering documentation. Utilization Categories AC-3, AC-4, AC-1 For motor, resistive, and mixed loads. Switching Capacity • Rated Making Capacity (Icm): ~2000 A (peak). • Short-circuit Withstand: Requires backup protection (fuse/circuit breaker). Mechanical Life ≥ 10 million operations Electrical Life (AC-3) ≥ 1.0 million operations at full rated load (200A) Common Inclusions (Interpretation of B25) Likely includes a minimal set of built-in auxiliary contacts (e.g., 1 NO + 1 NC) for basic feedback. It likely does NOT include a manual operator handle, electric charging motor, or other advanced accessories by default. This must be confirmed with the specific datasheet for GSH202 B25. Mounting Standard foot mounting for panel installation. Operation Purely electrical. Lacks a manual rotary handle for local operation. Must be operated by energizing/de-energizing its coil.
