AGH251S is an industrial-grade Coupling Device / Ankoppelgerät under the German brand BENDER.
This device is usually used as a core accessory together with BENDER insulation monitors (such as the A-ISOMETER series). Its core function is to extend the measuring voltage range of insulation monitors to higher-voltage IT ungrounded systems, so as to realize real-time online monitoring of system insulation resistance.
