Circuit Breaker Eti-Polam 3P B 10A (002115514) — three-pole B-characteristic, 10 A

Three-pole circuit breaker Eti-Polam 3P B 10A is a compact protective device designed for three-phase installations. With a B tripping characteristic and a nominal current rating of 10 A, this DIN-rail mountable breaker provides overcurrent and short-circuit protection for distribution boards in residential and light commercial environments. The device is intended for installation in standard enclosures and integrates into common electrical distribution systems to help maintain circuit safety and continuity.

Advantages

The three-pole design ensures simultaneous disconnection of all three phases for safer maintenance and reduced risk of phase imbalance. The B tripping characteristic provides sensitive protection against moderate overloads and short circuits typical for lighting circuits, small motor loads and general-purpose branch circuits. Compact dimensions and DIN-rail compatibility simplify installation in crowded distribution panels and reduce space requirements. The device is constructed to meet standard electrical safety practices for reliable day-to-day operation.

Suitable for

• Residential three-phase distribution boards
• Small commercial premises and light industrial circuits
• Protection of lighting circuits and general-purpose branch circuits
• Applications requiring coordinated three-pole disconnection

Key specifications

• Poles: 3 (three-pole)
• Tripping characteristic: B (type B)
• Nominal current: 10 A
• Mounting: DIN-rail compatible
• Function: overcurrent and short-circuit protection
• Typical application: three-phase circuits in residential and light commercial installations

How to use

Install the breaker on a standard DIN rail inside the distribution board according to local wiring rules and the system schematic. Ensure all power is isolated before connecting line and load conductors. Tighten terminals to the manufacturer's recommended torque and verify correct phase sequence and neutral connections where applicable. After installation, switch the device on and perform functional checks by applying load gradually to confirm correct tripping behavior at overload conditions. For complete installation details, follow applicable national electrical codes and wiring practices.

Usage recommendations

Use this breaker in circuits where a B characteristic is appropriate, such as lighting and typical branch circuits with limited inrush currents. Avoid using B-characteristic breakers for circuits with high motor starting currents; select a device with a suitable tripping curve for such loads. Periodically inspect connections for tightness and signs of overheating, and test the distribution board protection coordination after any circuit modifications.
