Frequently Asked Questions
Can I use this for a Direct-On-Line (DOL) motor starter?
Yes — this is a common choice for DOL circuits, with the green button providing the N.O. start contact and the red button the N.C. stop contact from a single 22mm panel cutout.
Does it work with variable speed/inverter drives?
Yes — it can be wired to VSD/inverter drive input terminals for manual start/stop control, not just direct motor contactors.
Can I add a running indicator?
Yes — an optional green LED (part CB9 for 12-30V, CBY for 230V) fits behind the clear centre lens to show running status.
Can I reconfigure or add more contacts?
Yes — additional EMAS C1 (N.O.) and C2 (N.C.) contact blocks can be added and double-stacked where panel space allows, letting you change or expand the standard 1NO+1NC arrangement.
