Technical Parameters Parameter Category Specification Notes Base Device GSH202 AC 200A frame high-performance contactor. AC indicates an AC-operating coil, but the exact voltage (e.g., 230V) is not specified here and must be provided as a separate part of the full order code. Main Circuit Ratings • Rated Operational Current (Ie) 200 A (at AC-3, 400V) • Rated Operational Voltage (Ue) Up to 690 V AC Mounting/Accessory Package -D16 Specific mechanical/accessory code. In GSH series coding: • D often denotes a specific mounting style, terminal configuration, or a version without a prominent front manual handle (compared to C codes). It may indicate a flush or compact design intended primarily for electrical operation. • 16 is a variant code, likely specifying details like included auxiliary contacts, terminal types, or mounting bracket style. Critical Special Feature /0.03 Integrated 0.03A (30mA) fuse for the control coil circuit (terminals A1-A2). Control Coil Fuse (/0.03) Core Protective Feature • Purpose To protect the external control power source from damage in case of a short circuit in the contactor's coil or its wiring. Safeguards PLC outputs, relay contacts, or small control transformers. • Rating 30 mA, gG or similar. • Location Integrated within the contactor assembly, often in a dedicated, accessible compartment. Control Coil AC (type specified). Coil voltage is a separate, mandatory specification. Example full order code: GSH202 A230 -D16/0.03 Utilization Categories AC-3, AC-4, AC-1 For motor and resistive load switching. Switching Capacity • Making Capacity (Icm): ~2000 A (peak). • Short-circuit Withstand: Requires backup fuse/circuit breaker. Mechanical Life ≥ 10 million operations Electrical Life (AC-3) ≥ 1.0 million operations at full rated current (200A) Typical Inclusions (Interpretation of -D16) Likely includes a basic set of built-in auxiliary contacts (e.g., 1NO+1NC) for status feedback. It likely does NOT include a front manual rotary handle for local operation. Must be confirmed with specific documentation for -D16. Mounting Standard foot mounting or as defined by the D package. Operation Primarily electrical via its coil. Lacks a manual operator handle.
