The 1600 A figure holds across the full voltage range from 220 V to 690 V AC, so derating is not required for higher line voltages. Short-time withstand current is 32 kA for 3 seconds, and short-circuit making capacity hits 135 kA at 690 V AC — meaning this frame can close onto a fault and ride through a bolted short without welding contacts or bursting the enclosure. Pollution degree 3 (industrial environment, conductive pollution) is designed in, so it lives reliably in panel environments without conformal coating. ## Deployment context Fixed-mounted, front-front connection, 70 mm pole pitch. The 350 mm width × 535 mm height × 160 mm depth frame fits into a standard distribution cubicle or MCC bucket. IK07 impact resistance handles accidental tool strikes during panel work.","metaTitle":"C16BS4FM ComPacT NS1600b Switch Disconnector, 1600A 4P","metaDescription":"Active ComPacT NS1600b switch disconnector basic frame, 1600A AC-23A, 690V, 4P fixed.
