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, 15VDC for
A, B, C, U, V contacts, 7A, 15VDC for W contacts with suitable arc-
suppression 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.
