Circuit breaker ETI Polam ETI Polammat 10 1P B 10A 10kA DC

The ETI Polam ETI Polammat 10 1P B 10A 10kA DC is a single-pole miniature circuit breaker designed for direct current installations. It delivers overcurrent and short-circuit protection for residential and light commercial DC circuits, helping to safeguard wiring, photovoltaic systems, battery banks and DC-fed equipment. The device mounts on standard DIN rails and features a compact housing suitable for distribution boards and control cabinets where space is limited.

Advantages

This miniature circuit breaker provides reliable thermal-magnetic tripping with a B-type characteristic, offering fast response to short-circuit faults while tolerating moderate inrush currents. With a rated current of 10 A and a breaking capacity of 10 kA, it is appropriate for many small-scale DC protection tasks. The single-pole configuration simplifies installation and reduces required panel space; the product’s rugged construction ensures consistent performance in typical indoor electrical environments.

Suitable for

• Protection of DC circuits in photovoltaic (solar) arrays and inverters
• Protection of battery systems and charge controllers
• Overcurrent protection for DC-powered lighting and control circuits
• Use in residential and light commercial DC distribution panels

Key specifications

• Poles: single-pole (1P) for one DC conductor
• Tripping characteristic: type B (thermal-magnetic)
• Rated current: 10 A
• Breaking capacity: 10 kA (short-circuit interrupting capability)
• Application: designed for direct current (DC) circuits
• Mounting: DIN-rail compatible housing for distribution boards

How to use

Install the circuit breaker on a compatible DIN rail inside the distribution board, ensuring power is disconnected before starting work. Connect the DC positive conductor to the breaker’s input terminal and the load conductor to the output terminal, observing proper torque values for terminal screws and polarity for DC systems. After installation, switch the breaker on and verify correct operation by testing the protected circuit under expected load conditions. Periodic visual inspections and functional tests are recommended to confirm the breaker operates as intended.

Usage recommendations

Select this 10 A, 10 kA DC miniature breaker when you require overcurrent protection for small DC circuits with moderate fault levels. Confirm the system’s maximum prospective short-circuit current does not exceed the breaker’s breaking capacity, and coordinate the tripping characteristic with upstream and downstream protective devices to ensure selective protection.
