FAQs
Install the 3P MCCB with fixed front terminals to simplify wiring and inspection. Use appropriate torque on terminal screws, align with Isomax mounting guidelines, and verify clearances for safe operation. The device’s front-terminal design reduces reach and wiring errors during commissioning and maintenance.
The device is 3P, 400 A, rated for 600 V AC with an 8 kV impulse withstand. It uses PR211/Li release for overcurrent protection, offers a short‑circuit capability up to 100 kA at 380 V, and delivers a stable, reliable cut-off under fault conditions in automated environments.
Yes. It carries a CE declaration (1SDL000160R0032) and RoHS compliance (1SDL000194R0001), aligning with IEC 947-2 standards for safe operation in regulated markets and enabling compliant procurement across sites.
Best for main feeders and machine protection in automation lines, production cells, and distribution panels. Its Isomax S5L compatibility, 3P configuration, and front-terminal mounting make it ideal for rugged industrial environments requiring reliable fault clearance and scalable protection.
Leverage its fixed, front-terminal design to minimize wiring complexity and downtime. With a 400 A rating, 600 VAC operation, and 7,000 electrical durability cycles, maintenance windows shorten, safety improves, and panel space is used efficiently, delivering measurable uptime and lifecycle cost reduction.
