NS and NSL contactor relays

Technical data

Magnet system characteristics for NS contactor relays
Contactor relay types AC operated NS
Coil operating limits AC supply
acc. to IEC 60947-5-1 0.85...1.1 x Uc (at θ ≤ 60 °C); Uc (at θ ≤ 70 °C)
AC control voltage Rated control circuit voltage Uc at 50 Hz 24...415 V
at 60 Hz 24...415 V
Coil consumption Average pull-in value 50 Hz 33 VA
60 Hz 33 VA
50/60 Hz 33 VA
Average holding value 50 Hz 6.5 VA / 1.5 W
60 Hz 5 VA / 1.2 W
50/60 Hz 6.5 VA / 1.5 W 05
Drop-out voltage Approx. 30...50 % of Uc
Operating time
Between coil energization and: N.O. contact closing 9...24 ms
N.C. contact opening 6...18 ms
Between coil de-energization and: N.O. contact opening (1) 5...19 ms
N.C. contact closing (1) 7...22 ms
(1) The use of RC5-1 surge suppressor increases opening time by a factor of 2 to 3.

Magnet system characteristics for NSL contactor relays
Contactor relay types DC operated NSL
Coil operating limits DC supply
acc. to IEC 60947-5-1 0.85...1.1 x Uc (at θ ≤ 60 °C); Uc (at θ ≤ 70 °C)
DC control voltage Rated control circuit voltage Uc 12...240 V DC
Coil consumption Average pull-in value 3 W
Average holding value 3 W
Drop-out voltage Approx. 10...40 % of Uc
Coil time constant Open L/R 12 ms
Closed L/R 40 ms
Operating time
Between coil energization and: N.O. contact closing 36...59 ms
N.C. contact opening 31...53 ms
Between coil de-energization and: N.O. contact opening (1) 13...17 ms
N.C. contact closing (1) 15...20 ms
(1) The use of RT5 surge suppressor increases opening time by a factor of 1.1 to 1.2.
