Why it matters for your setup: in three-phase distribution, a 4-amp trip device ensures you can protect small motors, control circuits, and auxiliary loads without nuisance trips in normal operation. The 3-pole design streamlines wiring in panelboards and motor control centers, reducing installation time and improving fault isolation.

Ideal use cases include:

• Three-phase motor control centers and machinery where compact protection is critical
• Panelboards and switchboards in manufacturing, packaging, and processing lines
• OEM equipment where reliable overcurrent protection in a 3-phase circuit is required

What makes this Cutler Hammer breaker stand out:

• Precise 4 A protection level—enables safe operation of low-power three-phase circuits
• Three-pole configuration minimizes wiring complexity and ensures simultaneous trip across all phases
• Designed for rugged industrial, commercial, and OEM environments, delivering consistent performance in distribution panels and motor control centers

Practical tips for best results:

• Verify compatibility with your panelboard or switchboard labeling and ensure correct mounting hardware for a 3-pole unit
• Plan conductor sizing to match the 4 A rating and protect downstream devices without nuisance tripping
• Consider this unit as part of a broader protection strategy for small motors and auxiliary circuits in three-phase systems

In short, the SPCL3C04 is a purpose-built solution for reliable overcurrent protection in three-phase environments, offering a compact, easy-to-install, and dependable option for panel assemblies, motor control centers, and OEM equipment that demand precise current protection without compromise.
