Three Pole Circuit Breakers

A three pole circuit breaker is the essential protection device for every three-phase electrical system — simultaneously disconnecting all three live conductors the moment it detects an overload or short circuit. Clopal brings you Pakistan's most complete range of 3 pole circuit breakers, covering standard AC MCBs, heavy-duty moulded case breakers, and earth leakage models — from compact residential ratings all the way up to 100 amp industrial-grade protection, all at the best 3 pole breaker price in Pakistan.

What is a Three Pole Circuit Breaker?

A three pole circuit breaker, also referred to as a 3 pole breaker or breaker 3 pole, is a protection device that monitors and simultaneously interrupts all three live conductors of a three-phase electrical system in a single trip action. This is the defining advantage of the three pole breaker — when a fault occurs on any one phase, all three phases are disconnected at once, preventing dangerous unbalanced voltage conditions that can burn out three-phase motors, compressors, and industrial equipment.

Unlike a three pole switch, which only manually opens or closes three conductors with no automatic protection, a three pole circuit breaker actively monitors current on all three phases and trips automatically on overload or short circuit — without any manual intervention. This makes the MCB 3 pole the standard protection choice for three-phase panels, commercial buildings, factories, and industrial control boards across Pakistan.

Dual-Mode Protection Across All Three Phases

Every Clopal MCB 3 pole delivers the same reliable dual-mode protection system across all three conductors simultaneously:

• Thermal Protection — A bimetallic strip on each of the three poles heats up and bends during sustained overload conditions, tripping all three phases together before heat can damage wiring, insulation, or connected equipment. The thermal response is deliberately gradual, allowing brief startup surges from three-phase motors and heavy machinery without nuisance tripping.

• Magnetic Protection — During a short circuit, a powerful induced magnetic field triggers an instantaneous simultaneous trip across all three conductors, interrupting fault currents in milliseconds to minimize damage to equipment and wiring.

All three poles trip together as a single coordinated unit — ensuring no phase remains energized after a fault, which is critical for the safe maintenance of three-phase systems and full compliance with IEC 60898 electrical safety standards.

Complete Range of Three Pole Circuit Breakers

Clopal's three pole circuit breaker collection covers the full spectrum of current ratings for every three-phase application:

Standard AC Three Pole MCBs

• 10A, 16A, 20A, 25A — For light commercial three-phase panels, office buildings, and low-load industrial applications

• 32A, 40A — For medium-load three-phase circuits including HVAC systems, pumping stations, and workshop machinery

• 63A — Heavy-load three-phase protection for large commercial establishments and light industrial setups

Heavy-Duty Moulded Case Three Pole Breakers

• 100A Three Pole Breaker — The Clopal 3 pole breaker 100 amp is a heavy-duty moulded case circuit breaker (MCCB) designed for main incomer protection, industrial distribution boards, and high-current three-phase systems where standard MCBs are insufficient

All standard MCB 3 pole models are built for DIN Rail mounting (EN60715, 35mm) with a fast-clip mechanism for quick, secure installation in any three-phase distribution board or control panel. Terminal wiring supports up to 25mm² conductors with a tightening torque of 2.5Nm for solid, safe connections every time.

3 Pole Breaker 100 Amp — Heavy-Duty Industrial Protection

The 3 pole breaker 100 amp is a class apart from standard MCBs. Built as a moulded case circuit breaker (MCCB) with a heat-resistant porcelain body, the Clopal 100A three pole breaker delivers high breaking capacity, exceptional durability under load, and reliable protection for main panels, factory distribution boards, and heavy industrial three-phase circuits. If your application demands more than a standard MCB 3 pole can offer — the 100 amp MCCB is your answer.

3 Pole Changeover Switch — Generator & Mains Transfer

In addition to standard MCBs and MCCBs, Clopal also offers the 3 pole changeover switch — an essential device for safely transferring a three-phase circuit between two power sources, such as WAPDA mains supply and a generator. A 3 pole changeover switch simultaneously transfers all three phases together, preventing any risk of backfeed or dangerous parallel connection between two sources. This makes it the standard transfer device for factories, commercial buildings, hospitals, and industrial facilities running three-phase generator backup.
