NOTES
1. All values at 20°C (68°F).
2. Maximum make current refers to in-rush current of lamp load.
3. Electrical life obtained at resistive or inductive load of 10A,
15 VDC for A, B, C, U, V contacts, 7A, 15 VDC for W contacts
with suitable arcsuppression circuit attached with operating
frequency of 1 ops/sec.
4. Relay may pull in with less than “Must Operate” value.
5. Specifications subject to change without notice.
