Schneider Electric C160H42AFM ComPacT NS1600H 4P 1600 A 70 kA MicroLogic 2.0 A Moulded Case Circuit Breaker

The Schneider Electric C160H42AFM is a 4-pole, 1600 A ComPacT NS1600H moulded case circuit breaker rated for 70 kA breaking capacity (Icu) at 380/415 V AC. Fixed-mounted and manually operated, it carries a MicroLogic 2.0 A electronic trip unit delivering long-time overload and instantaneous short-circuit protection, and is rated up to 690 V AC for high-breaking-capacity distribution duty in the ComPacT NS630b...1600 new generation line.

Selection Notes

The H-frame classification gives the C160H42AFM 70 kA Icu at 380/415 V AC — choose it over the N-frame version of the same 1600 A frame when prospective short-circuit current at the installation point runs above standard distribution levels. Its MicroLogic 2.0 A trip unit covers long-time overload and instantaneous protection only (LI), with no short-time delay stage — choose a 5.0 (LSI) or 6.0 (LSIG) trip unit from this same frame where selective coordination with downstream breakers is required. The A suffix adds a digital LCD screen with an RMS ammeter, giving it a local current readout without a separate meter. With 4 poles and a neutral protection setting adjustable between 0.5× Ir (3D + N/2) and 1× Ir (4D), it suits TN-S or TT systems that need their own neutral overload protection; the 3-pole version of the same frame is for 3-phase-only loads.
