     Contact protection relay, model: MSR 4. Regulation Use Any use of the contact protection relay, model MSR, which exceeds the manufacturer’s specifications may invalidate its warranty. Therefore, any resulting damage is not the responsibility of the manufacturer. The user assumes all risk for such usage.

  • Page 4: Operating Principle

    The switching operation is thus clearly defined. Type MSR-011 is a bistable interval relay with latching and is thus suitable for an interval switching, for example for pump control. Design and construction of the contact protection relay satisfy VDE regulations 0110 insulation class c/250 V.

    N and L. When the supply voltage has been switched on (and the connected limit value switch is not operated, i.e., contact is open) the potential free change-over contact of the MSR-relay is non-operative (see type plate). By operating the limit value switch (contact is closed) the change-over contact is energized.

    L and N. When the supply voltage has been switched on (and the connected limit value switch is not operated, i.e.; contact is open) the potential free change-over contact of the MSR-relay is non-operative (see type plate). By operating the limit value switch (contact is closed) the change-over contacts are energized.

    Only when contact is closed (contact has no influence on the switching behaviour any longer) the potential-free change- over device of the MSR relay returns to its inoperative condition (see type plate). If contact of the limit value switch opens again, the contacts at the change-over contact remain inoperative.
