Circuit breaker Eti-Polam ETIMAT10 1P B 20A 10 kA AC (MPN 002121717)

The Eti-Polam ETIMAT10 single-pole miniature circuit breaker with B characteristic and a rated current of 20 A provides overcurrent protection for low-voltage AC installations. Designed for DIN-rail mounting in residential and light commercial distribution boards, this circuit breaker interrupts fault currents up to 10 kA (AC breaking capacity) and safeguards wiring and connected equipment from overloads and short circuits. The compact single-pole design fits standard distribution enclosures and is compatible with common busbar and terminal connections used in household and small commercial electrical installations.

Advantages

The ETIMAT10 B20 combines a clear thermal-magnetic tripping characteristic with reliable breaking capacity, ensuring predictable response to overloads and short circuits. Its compact form factor saves space in distribution panels while providing consistent mechanical and electrical performance. The product is designed for straightforward DIN-rail installation and secure terminal tightening, offering long-term service life under typical residential and light commercial operating conditions.

Suitable for

• Protection of lighting and socket circuits in homes
• Overcurrent protection for small workshops and light commercial premises
• Individual circuit protection for appliances and consumer units
• Replacement or upgrade of single-pole breakers in distribution boards

Key specifications

• Poles: single-pole (1P)
• Tripping characteristic: type B (sensitive to short-circuit and moderate inrush currents)
• Rated current: 20 A
• Breaking capacity: 10 kA (AC)
• Mounting: DIN-rail compatible
• Application voltage: suitable for low-voltage AC distribution systems
• Form factor: miniature circuit breaker for standard distribution panels

How to use

Install the circuit breaker on a standard DIN-rail inside the distribution board, ensuring the supply is isolated before starting work. Connect the line conductor to the designated terminal and the load conductor to the outgoing terminal, observing correct tightening torque for secure connections. After installation, restore supply and verify correct operation by switching the breaker on and off. In case of repeated tripping, identify and remedy the underlying overload or short-circuit condition before resetting the breaker.

Usage recommendations

Use this B-type 20 A breaker where protection for general-purpose circuits with limited inrush currents is required, such as lighting and socket outlets. For circuits with higher motor starting currents or sensitive electronic loads, consider selecting a different tripping characteristic or additional protective devices. Regular visual inspection and periodic testing during maintenance are recommended to ensure continued reliability.
