Installation switch, redundant current circuit breaker, DS type installation switch also colloquially called eska – an element of electrical installation whose task is to break the continuity of the circuit,
when the current flowing in this circuit exceeds the safe value for this circuit.
These switches are designed to control and protect against the effects of overcurrents (overloads and short circuits)
receiving circuits of electrical installations and appliances in households and others.
PARAMETERS:
Max. cross-section of connected wires mm2: 1...25
-Mounting on a standard 35 mm DIN rail
-Ambient temperature: -25...+60 deg. C
-Operating rated voltage Ue, V: AC 230/400
-Rated frequency Hz: 50
-Number of poles: 3
-Torque of tightening contact terminals Nm: 3
-Time-current characteristics: B
-Rail connection method: Upper and lower
-Nominal shutdown capacity Inc kA: 6
-Nominal current In, A: 20
