What Makes Omch MCB Stand Out?

Guaranteed Stability

Triple-welded critical contacts and flame-retardant materials ensure non-combustibility and pass repeated tripping tests, fundamentally eliminating disposable failure issues.

Precision Craftsmanship

Burr-free precision machining with virgin materials (no recycled content), allowing cross-sectional inspection to verify authentic materials and superior workmanship.

Reusable & Economical

Manual reset design allows reuse after fault clearance without part replacement, significantly reducing long-term maintenance costs, ideal for frequent operations.

Precise Protection

Type B/C/D tripping curves accurately distinguish overload from startup currents, preventing nuisance tripping for motors and inductive loads.

Visual Status

Clear mechanical switch position ("ON/OFF") enables quick fault circuit identification, drastically improving maintenance efficiency versus fuses.

Pure Overcurrent Protection

Focuses solely on overload/short-circuit protection without leakage detection, ensuring stable operation in dry environments.

Not just a supplier,
but your trusted long-term partner in success.
