Circuit breaker Eti-Polam ETIMAT10 3P C 63A 6kA (model 002135722)

Three-pole Eti-Polam ETIMAT10 circuit breaker with C-characteristic, nominal current 63 A and breaking capacity 6 kA is designed for overload and short-circuit protection in low-voltage electrical installations. The device provides combined thermal-magnetic protection across three poles, enabling coordinated tripping for circuits that require both reliable overload handling and decisive short-circuit interruption. It is intended for use in distribution boards, sub-distribution panels and industrial or commercial electrical systems where selective tripping and consistent performance are needed.

Advantages

The three-pole construction ensures simultaneous disconnection of all phases to maintain safety and prevent phase-to-phase faults. The C-characteristic trip curve offers a balance between sensitivity to short-circuit events and tolerance for temporary inrush currents from motors or transformers. A 63 A nominal current rating supports a range of branch-circuit loads, while the 6 kA breaking capacity suits typical commercial and light-industrial applications. The unit’s compact form factor facilitates installation in standard DIN-rail distribution enclosures.

Suitable for

• Protection of three-phase branch circuits in commercial and light-industrial installations
• Use in distribution boards and sub-distribution panels
• Circuits supplying motors, transformers or mixed resistive/inductive loads with moderate inrush currents

Key specifications

• Poles: 3-pole thermal-magnetic protection
• Trip characteristic: Type C (moderate instantaneous trip threshold)
• Nominal current: 63 A
• Breaking capacity: 6 kA (short-circuit interrupting capability)
• Mounting: DIN-rail compatible form factor for standard distribution enclosures

How to use

Install the circuit breaker on a standard DIN rail inside the distribution board, ensuring correct phase ordering and secure terminal connections according to the system wiring diagram. Tighten terminals to the manufacturer’s recommended torque and verify correct phase continuity before energizing. Use the breaker as the protective device for the designated three-phase feeder or branch circuit; during commissioning, check trip coordination with upstream and downstream protective devices to ensure selectivity where required.

Usage recommendations

Perform periodic inspection and retightening of terminals, verify thermal loading and ambient conditions, and test trip operation as part of routine maintenance. Confirm coordination with upstream protective devices for selective tripping in multi-level protection schemes. Replace the breaker if physical damage or signs of thermal stress are observed.
