Ls 400V - 63A, 4-Pole, Circuit Breaker

Product description
Shipping

The LS 400V - 63A, 4-Pole Circuit Breaker is built for dependable overcurrent protection in demanding electrical environments. With a 63A rating and a 4-Pole configuration, this breaker isolates all three phases plus the neutral when faults occur, delivering safe, coordinated shutdowns in one compact unit.

Why the 4-Pole design matters

In three-phase systems, a 4-Pole circuit breaker provides complete interruption across every active conductor. This means safer maintenance, reduced risk of neutral backfeed, and cleaner startup sequences for equipment in motor control centers, panelboards, and switchboards.

Key specifications

  • Voltage rating: 400V
  • Current rating: 63A
  • Poles: 4-Pole
  • Breaker type: Circuit Breaker

Ideal applications

  • Industrial panelboards and switchboards requiring reliable overcurrent protection
  • Motor control centers where consistent fault interruption is critical
  • Commercial and OEM distribution panels that demand safe, predictable operation

What it solves for you

  • Protects sensitive equipment from overcurrent events, minimizing downtime and equipment damage
  • Provides full-phase isolation, enhancing safety during maintenance and fault recovery
  • Offers flexible integration into existing 4-pole layouts, simplifying upgrades and replacements

Why choose LS for protection you can trust

This LS circuit breaker is purpose-built for environments where dependable protection and safe operation are non-negotiable. It’s designed to stand up to industrial workloads, deliver consistent performance in distribution panels and motor centers, and support long-term reliability for facilities that run on 400V three-phase power.
