Circuit breaker 1P B 13A Eti-Polam model 002111515

Circuit breaker 1P B 13A Eti-Polam model 002111515 is a single-pole miniature circuit breaker designed for installation on standard DIN rails in residential and light-commercial distribution boards. It provides overcurrent protection with a B-type trip curve and a rated current of 13 amperes, suitable for general-purpose circuits and protection against short circuits and overloads. The device is compact and intended for integration with typical electrical installation components.

Advantages

The B-type characteristic ensures fast response to moderate short-circuit currents while allowing harmless inrush currents of lighting and small appliances. Its single-pole design simplifies wiring for phase conductor protection in single-phase systems. The compact DIN-rail form factor permits space-efficient layout in distribution panels and straightforward replacement of like-for-like breakers.

Suitable for

• Protecting general lighting and socket circuits in homes and apartments
• Small commercial spaces with low to moderate load requirements
• Circuits with motors and appliances that have limited inrush currents
• Standard DIN-rail electrical distribution boards and consumer units

When it may not be suitable

This B-type 13A single-pole breaker is not intended for protection of three-phase circuits, high inrush current loads such as large motors, or circuits that require selective coordination with upstream protection devices having different characteristics. It also does not provide residual-current (earth leakage) protection; a separate RCD/RCBO is required where earth-fault protection is mandated.

Key specifications

• Poles: single-pole (1P)
• Rated current: 13 A
• Tripping characteristic: B-type (standard thermal-magnetic response)
• Mounting: DIN-rail compatible
• Function: overcurrent protection for short-circuit and overload conditions

How to use

Install the circuit breaker on a standard DIN-rail inside the distribution board, connecting the phase conductor to the breaker input terminal and the protected circuit to the output terminal. Ensure proper tightening of terminals to the torque values specified by the panel designer or local electrical regulations. Use the front toggle to switch the breaker on or off during maintenance; if the breaker trips, identify and remove the fault before resetting. All installation and maintenance procedures should be carried out by a qualified electrician in accordance with local codes.

What to consider before purchase

• Verify that a 13 A rated current and B-type characteristic match the load and coordination requirements of your installation
• Ensure compatibility with the distribution board's DIN-rail spacing, terminal type, and available clearance
• Check local regulations for the need to pair with residual-current devices where earth-fault protection is required

Usage recommendations

Use this single-pole B 13A breaker for phase conductor protection in standard single-phase circuits where moderate short-circuit sensitivity and allowance for inrush currents are acceptable. For circuits with higher starting currents, three-phase equipment, or requirements for integrated earth-fault protection, select an appropriate alternative device.
