Circuit breaker Etipo ETI Polam Asti Etimat 10 272000100 1P B 20A 10kA AC

Etipo ETI Polam Asti Etimat 10 single-pole miniature circuit breaker B curve 20 A is a compact protective device for overcurrent protection in residential and light commercial electrical installations. The breaker uses a thermal-magnetic mechanism to trip on overloads and short circuits, and is designed for installation on a standard 35 mm DIN rail. With a rated nominal current of 20 A and a breaking capacity suitable for typical distribution boards, it is intended to protect branch circuits and connected equipment from excessive currents.

Advantages

The single-pole design conserves panel space while providing reliable thermal-magnetic protection for overload and short-circuit conditions. The B curve characteristic ensures fast tripping on moderate short-circuit currents while avoiding nuisance trips from inrush currents of small motors and lighting loads. Its compact dimensions and DIN-rail mounting enable straightforward integration into standard consumer units and small distribution boards. The device is engineered to meet applicable safety and performance practices for miniature circuit breakers.

Suitable for

• Protection of lighting circuits in homes and apartments
• Branch circuit protection for sockets and small appliances
• Electrical panels in small commercial or utility rooms
• Replacement of single-pole breakers in compatible distribution boards

Key specifications

• Poles: single-pole (1P)
• Tripping characteristic: B curve (thermal-magnetic)
• Rated current: 20 A
• Rated breaking capacity: 10 kA (AC)
• Mounting: 35 mm DIN rail
• Application: overcurrent protection for residential and light commercial circuits

How to use

Install the circuit breaker into a compatible distribution board by snapping it onto the standard 35 mm DIN rail and making secure line and load connections according to local wiring rules. Ensure that the breaker is positioned in the correct pole location and that conductors are tightened to the recommended torque values. After installation, switch the device on and test the protected circuit under normal load conditions. For fault troubleshooting, switch off the breaker before inspecting wiring or downstream equipment. Installation and maintenance should be performed by a qualified electrician in accordance with applicable electrical codes.

Usage recommendations

Verify compatibility with the distribution board and the expected load profile before selection. Use the B curve 20 A breaker where moderate inrush currents may occur but where prompt short-circuit clearing is required. Periodically check terminals for tightness and visually inspect the breaker for signs of damage; replace if mechanical or electrical faults are detected.
