Circuit breaker Etipo ETI Polam Asti Etimat 10 1P B 50A 6kA DC

Single-pole Etipo ETI Polam Asti Etimat 10 circuit breaker with B trip curve, rated current 50 A and breaking capacity 6 kA DC. Designed for overcurrent protection in DC electrical circuits, it provides thermal-magnetic tripping to protect against short circuits and overloads in residential, commercial and small industrial installations. The device fits standard DIN-rail mounting and has a compact form factor for use in distribution panels where single-pole DC protection is required.

Advantages

The Etimat 10 1P B 50A provides combined thermal and magnetic protection to respond to both sustained overloads and sudden short-circuit events. With a B characteristic curve it offers sensitivity to moderate inrush currents typical for lighting and small motor circuits while maintaining reliable breaking performance up to 6 kA DC. Its single-pole design simplifies installation in DC systems and helps save space in electrical cabinets. The breaker is constructed for stable switching and consistent trip performance over its service life.

Suitable for

• Protection of DC lighting circuits and small DC motors
• Overcurrent protection in residential PV or battery systems with single-pole circuits
• Protection of control circuits and auxiliary DC supplies in commercial installations
• Small-scale industrial equipment requiring single-pole DC protection

• Pole count: single-pole (1P)
• Trip curve: B (thermal-magnetic characteristic)
• Rated current: 50 A
• Breaking capacity: 6 kA DC
• Mounting: DIN-rail compatible
• Application: DC circuits

How to use

Install the circuit breaker on a standard DIN rail inside the distribution enclosure. Connect the incoming DC supply conductors to the breaker terminals following polarity and torque specifications from the system documentation. Use appropriately sized conductors and protective accessories (fuses, surge protection) as required by the overall installation design. After installation, verify correct operation by switching the breaker on and off under no-load conditions and by testing the circuit under controlled load to confirm trip behaviour.

Usage recommendations

For safe and reliable operation, match the rated current and breaking capacity to the characteristics of the DC source and downstream loads. Ensure correct coordination with upstream and downstream protective devices, and follow local wiring regulations and installation standards. Periodic inspection and testing are advised to confirm mechanical integrity and trip performance, especially in environments with temperature extremes or vibration.
