RELAYS AND TIMERS
[13] Clip-on front mounting, 1 block per control relay.
[14] Auxiliary contact module not suitable for safety circuits.
[15] Not to be used on CA4KN relays.
[16] See “Clip-in Marker Strips” in Catalog
8501CT0101 for information on completing the catalog number.
[17] Protection by the limitation of the transient voltage to 2 Uc maximum. Maximum reduction of the transient voltage peaks. Slight time delay on drop-out (1.1 to 1.5 times normal).
[18] No overvoltage or oscillation frequency. Polarized component. Slight time delay on drop-out (1.1 to 1.5 times normal).
[19] Protection by limitation of the transient voltage to 3 Uc max. and limitation of the oscillation frequency. Slight time delay on drop-out (1.2 times to twice normal).
