GENERAL TECHNICAL DATA
CYCLE - Operate and subsequent release of a relay. Over a cycle the coil is energised and de-energised and the contact will progress from the point
at which it makes a circuit, through to breaking the circuit, to the point at which it re-makes the circuit.
PERIOD - The time covering one cycle.
DUTY FACTOR (DF) - During cyclic operation, DF is the ratio between the energised time and one period. For continuous duty, DF =1.
MECHANICAL LIFE - This test is performed by energising the coils of several relays at 8 cycles per second without any load applied to the con-
tacts. It establishes the ultimate durability of the relay where electrical wear of the contacts is not an issue. The maximum Electrical Life may therefore
approach the Mechanical Life where the electrical loading of the contacts is very small.
ELECTRICAL LIFE - See in CONTACT SPECIFICATIONS.
OPERATE TIME - The maximum operate time of contacts with the coil energised at rated voltage. In the catalogue, it includes the bounce time (see
following pattern).
RELEASE TIME - The maximum release time of contacts. In the catalogue, it includes the bounce time (see following pattern). It will increase if
protection modules are connected in parallel to the coil.
INSULATION COORDINATION according to EN 61810-5 - See in INSULATION DATA.
DIELECTRIC STRENGTH BETWEEN OPEN CONTACTS - See in INSULATION DATA.
AMBIENT TEMPERATURE RANGE - The range of temperatures of the immediate area where the relay is located, and for which operation of the
relay is guaranteed (under prescribed conditions).
ENVIRONMENTAL PROTECTION according to IEC 61810-7 - The relay technology categories describe the degree of sealing of the relay case:
