\"Early-Break\" auxiliary contacts in this device?\u003c\/strong\u003eEarly-break contacts are a safety feature. They change state slightly before the main poles disconnect. This allows a PLC or safety relay to detect the disconnection intent and electronically shut down sensitive components (like variable speed drives or motor contactors) to prevent arcing across the main disconnector poles under load.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use this disconnector for DC power circuits?\u003c\/strong\u003eThe power circuit rating is specified for 690 V AC. While the signaling circuit is rated for 440 V DC, using the main poles for high-current DC disconnection requires specific de-rating and verification of the arc-extinguishing capabilities for DC.
