FAQ
What is the difference between MCB and MCCB?
MCBs (Miniature Circuit Breakers) are for low-current applications (≤100A), typically residential/commercial, with fixed trip settings. MCCBs (Molded Case Circuit Breakers) handle higher currents (10A–630A+), industrial/commercial use, and offer adjustable trip settings and higher breaking capacity.
What is a MCCB used for?
MCCBs protect electrical circuits and equipment from overload, short circuits, and under-voltage faults in industrial, commercial, and marine power distribution systems, including machinery, panels, and critical infrastructure.
What is MCB, MCCB, and RCCB?
- MCB: Low-current (≤100A) breaker for residential/commercial overload/short-circuit protection.
- MCCB: High-current (10A–630A+) breaker for industrial/commercial systems with adjustable protection.
- RCCB: Residual Current Circuit Breaker, detects earth leakage to prevent electric shock (no overload/short-circuit protection alone).
Is an MCCB an RCD?
No. MCCBs focus on overload/short-circuit protection, while RCDs (Residual Current Devices, e.g., RCCB) specifically detect leakage currents. Some MCCBs may integrate RCD functions as an accessory.
What types of MCCB are available?
Available by frame size (125A–630A), poles (3P/4P), trip units (thermal-magnetic/electronic), and applications (distribution/motor protection).
What certifications do your MCCBs have?
Compliant with international standards like IEC 60947-2, with mainstream safety certifications for global markets.
Do you support OEM customization for MCCBs?
Yes, OEM services are available, including custom parameters, branding, and packaging.
What is the lead time for MCCB orders?
Lead times vary by region, typically 2–4 weeks. Contact sales for exact delivery timelines.
