Product Description
Chtaixi DC Minuscule Circuit Breaker
Helpful Hint:
Take note of polarity. Choose wire dimension according to the rated current.
Magnetic Arc Extinction
AC features a zero-crossing point, unlike DC, which makes extinguishing a DC arc more challenging than that of an AC arc. Consequently, AC circuit breakers are not suitable for DC applications, though DC circuit breakers can work with AC power. This DC mini circuit breaker is outfitted with a magnetic field system beneath the breaking contacts, which draws the arc into the extinguishing chamber to facilitate arc extinction.
High-Quality Products for Your Electrical Safety
Polarity Indicated
This DC MCB does not necessitate polarity during its operation, allowing for the positive and negative poles to be reversed. However, the installation, utilization, and upkeep of DC circuits hinge on polarity specifications. Thus, to ensure dependable indication and reference for the distribution, we strongly advise connecting the wires in accordance with the marked polarity.
Tunnel Connection
The terminal block’s clamping structure ensures a solid connection, requiring a tightening torque of 2.5 N.m. (Soft silicone wire should be secured with copper crimp before connecting). Verify that the wires are tightly connected during installation to avoid loosening and overheating. The terminal surface is tin-plated, enhancing conductivity, corrosion resistance, and longevity.
Silver Alloy Contacts
Contacts are crucial to circuit breakers, particularly in DC distribution where high arc extinction demands exist. Superior contacts can minimize the heat produced by arcing during disconnection and lessen the wear on the contacts. This DC circuit breaker employs silver alloy contacts, enhancing its electrical durability and safeguarding your electrical safety over an extended period.
