Selection Notes

Without positive opening, this NO contact is a general control-logic block rather than a certified safety-interlock contact, so pick the 1 NC sibling with IEC 60947-5-1 Appendix K positive opening whenever the application needs a guaranteed-open contact for a safety circuit. The built-in metal fixing collar means this reference already includes the mounting hardware that a bare ZB4BZ009 collar would otherwise supply separately.
