Circuit breaker Eti-Polam ETIMAT10 3P C 20A 10kA AC (MPN 002135717)

Eti-Polam ETIMAT10 3P C 20A miniature circuit breaker provides three-pole protection for low-voltage electrical installations. The device features a C-type tripping characteristic and a rated current of 20 A, with a breaking capacity of 10 kA (AC). It is intended for mounting on standard DIN rails and protects circuits against overloads and short circuits in residential, commercial and light-industrial distribution boards where a compact, reliable protective device is required.

Advantages

The breaker combines a C-type instantaneous trip curve suited for general-purpose loads with a thermal magnetic mechanism for stable long-term overload protection. Its three-pole design ensures simultaneous disconnection of all phases for balanced safety in three-phase circuits. The compact housing and DIN-rail compatibility simplify installation in crowded distribution panels while maintaining a 10 kA breaking capacity for effective interruption of fault currents typical in low-voltage networks.

Suitable for

• Protection of three-phase lighting and socket circuits in residential buildings
• Main or sub-distribution boards in small commercial premises
• Light-industrial equipment with moderate inrush currents
• Retrofit or new installations on standard DIN rails

Key specifications

• Poles: 3-pole (simultaneous phase disconnection)
• Tripping characteristic: C-type (moderate instantaneous response)
• Rated current: 20 A
• Breaking capacity: 10 kA (AC)
• Mounting: standard DIN-rail
• Function: thermal-magnetic overload and short-circuit protection

How to use

Install the circuit breaker into the distribution board on a standard DIN rail, ensuring correct orientation and secure mechanical fastening. Connect the incoming supply conductors to the line terminals and the outgoing load conductors to the load terminals, observing phase sequence and tightening torque recommended by the panel manufacturer. After wiring, switch the device to the ON position and verify circuit continuity and correct operation with appropriate test equipment. If a fault occurs, the breaker trips automatically; identify and correct the fault before resetting the device.

Usage recommendations

Choose this 3-pole C-type, 20 A breaker where moderate inrush currents are expected and selective protection between upstream and downstream devices is required. Verify coordination with upstream protective devices and comply with local wiring regulations during selection and installation.
