Circuit breaker Eti-Polam ETIMAT10 3-pole B curve 50 A 6 kA

The Eti-Polam ETIMAT10 three-pole circuit breaker with B trip characteristic and a rated current of 50 A provides selective protection for three-phase circuits in residential and light commercial electrical installations. With a rated breaking capacity of 6 kA and a compact form factor for DIN-rail mounting, this ETIMAT10 device is designed to interrupt overloads and short-circuit currents while allowing coordination with downstream protective devices.

Advantages

The ETIMAT10 3-pole B curve 50 A offers precise thermal-magnetic tripping behavior suitable for standard resistive and lightly inductive loads, enabling reliable overload protection and fast response to short circuits. Its 6 kA breaking capacity ensures safe interruption of fault currents commonly encountered in small buildings. The product’s DIN-rail compatibility simplifies installation in distribution boards and switchgear, and its standardized form factor supports easy replacement or expansion of existing systems.

Suitable for

• Protection of three-phase circuits in residential electrical panels
• Light commercial installations such as small offices, shops or workshops
• Coordination with downstream devices like contactors and residual current devices
• DIN-rail distribution boards and modular switchgear assemblies

Key specifications

• Poles: 3 (three-pole)
• Tripping curve: B-type (thermal-magnetic characteristic)
• Rated current: 50 A
• Breaking capacity: 6 kA
• Mounting: DIN-rail compatible
• Application: overload and short-circuit protection for low-voltage circuits

How to use

Install the ETIMAT10 3-pole circuit breaker on a standard DIN-rail inside the distribution board, ensuring correct phase sequence and secure terminal connections tightened to the manufacturer’s recommended torque. Connect supply and load conductors to the appropriate line and load terminals, and verify that the device is accessible for manual operation. Before energizing the protected circuit, confirm that the breaker rating and B curve characteristic are appropriate for the connected loads and any downstream devices to maintain selectivity and safe operation.

Usage recommendations

Use this breaker in circuits where inrush currents are not excessively high compared to steady-state current, and coordinate with downstream protective devices to achieve discrimination. Periodically inspect terminal tightness and the breaker’s mechanical operation, and replace the device if it shows signs of overheating or mechanical wear.
