Hydra motor capacitors with pressure relief switch MKP-Si technology series 500.

Safety: Capacitors can fail under extreme operating conditions or after reaching their lifespan. Hydra motor capacitors are manufactured with an integrated pressure relief switch. In the event of failure, gas formation and temperature rise within the capacitor lead to an increase in pressure. This results in a housing extension of up to 9 mm due to the stretching of the folding seam, thereby interrupting the supply line at the predetermined breaking point. The capacitor is safely disconnected from the power supply. Hydra capacitors are certified by the VDE Testing and Certification Institute and comply with the safety class P2 requirements according to EN 60252.

Installation: Hydra motor capacitors can be mounted vertically or horizontally. To ensure proper triggering of the pressure relief mechanism due to the length expansion of the capacitor housing, a minimum distance of approximately 12 mm from the connection to adjacent components must be observed.

Construction: Metallized polypropylene, aluminum housing with or without metal studs, environmentally friendly filling material (plant oil).
