Circuit Breaker Etipo ETI Polam Asti Etimat 10 271030100 3P B 10A 10kA AC

Circuit Breaker Etipo ETI Polam Asti Etimat 10 3P B 10A 10kA AC is a three-pole miniature circuit breaker intended for overcurrent protection in low-voltage electrical installations. It provides thermal-magnetic tripping to protect circuits from overload and short-circuit conditions and is suitable for installation in distribution boards for residential and light commercial applications. The device is designed to interrupt fault currents up to 10 kA (AC) and has a B characteristic curve, which ensures reliable response to moderate inrush currents while protecting connected conductors and equipment.

Advantages

This three-pole breaker offers coordinated thermal and magnetic protection in a compact DIN-rail mountable format, enabling straightforward integration into standard distribution panels. With a nominal current rating of 10 A and a 10 kA breaking capacity, it balances protection capability and compact size for typical household and small-business circuits. The B tripping curve reduces nuisance tripping on circuits with limited inrush while still providing prompt disconnection during faults, and the robust construction supports stable performance in normal operating conditions.

Suitable for

• Protecting three-phase circuits in residential distribution boards
• Overcurrent protection for lighting and general-purpose sockets in light commercial spaces
• Use as a branch-circuit protective device for motors and small machinery with low starting currents

Key specifications

• Poles: 3-pole configuration for three-phase circuits
• Tripping type: Thermal-magnetic trip mechanism
• Tripping characteristic: B curve (suitable for circuits with low to moderate inrush)
• Rated current: 10 A nominal
• Breaking capacity: 10 kA (AC)
• Mounting: DIN-rail compatible for standard distribution boards
• Application voltage range: Designed for low-voltage AC distribution systems

How to use

Install the breaker on a standard DIN rail inside the distribution board, ensuring proper orientation and secure mechanical fastening. Connect the incoming line conductors to the line terminals and load conductors to the load terminals according to local wiring practices and the circuit diagram. Verify tightness of terminal screws and correct phase sequence for three-phase connections. After wiring, test the device by switching it on and verifying that the circuits are energized and that the breaker trips when an intentional test fault or overload condition is applied in a controlled manner. Always follow applicable electrical codes and safety procedures during installation and commissioning.

Usage recommendations

Choose the B characteristic breaker where normal operating inrush currents are low to moderate, and ensure the rated current matches the protected circuit conductors and connected load. Coordinate upstream and downstream protective devices to maintain selective operation and prevent unnecessary supply interruptions. Perform periodic inspections and functional tests according to local regulations to confirm reliable operation.
