ABB MCCB TP 63A 25KA A1C 125R63-68770R1 Formula

ABB A1C 125 TMF63 3-Pole Moulded Case Circuit Breaker

The A1C 125 TMF 63-630 is a fixed three-pole moulded case circuit breaker from ABB's SACE Formula range, rated at 63A with a thermomagnetic (TMF) release and front terminal connections. Designed for protection of feeders, distribution circuits, and machinery, it offers reliable overload and short-circuit protection suited to commercial and industrial installations across the UAE.

Key Features

• 3-pole moulded case circuit breaker with 63A rated current and 125A frame (Iu) rating
• TMF thermomagnetic release providing combined overload and short-circuit protection
• 25kA rated ultimate breaking capacity (Icu) at 415V, suited to standard commercial fault levels
• Front terminal connections for straightforward panel installation and wiring access
• Genuine ABB quality — 8,500 mechanical operating cycles for long-term reliability

Technical Specifications

Applications

• Feeder and distribution circuit protection in commercial and light industrial panels
• Motor and machinery circuit protection requiring combined overload and short-circuit trip
• Main or sub-main protection in low voltage distribution boards
• Panel builds across the UAE requiring compact, front-terminal MCCB protection

FAQ

• What's the difference between an MCB and an MCCB?
  An MCB (miniature circuit breaker) is typically rated up to 100A with a fixed, non-adjustable trip and lower breaking capacity, used for final circuits. An MCCB (moulded case circuit breaker) is built for higher currents and fault levels, and is used for main incomers, sub-mains, and feeder protection where an MCB's rating or breaking capacity would be insufficient.
• When do I need an MCCB instead of an MCB?
  Use an MCCB where the prospective fault current or load current exceeds what an MCB is rated to handle safely — typically at the main incomer or major sub-main level of a commercial or industrial distribution board.
• Does this MCCB have an adjustable trip setting?
  Check the specific trip unit type in the Technical Specifications table above — thermal-magnetic MCCBs may have a fixed or adjustable trip range depending on the model; an electronic trip unit typically offers configurable protection curves.
• Can I install this myself?
  No. MCCBs are installed in distribution boards and panels by a licensed electrician, in line with UAE wiring regulations.
