The HSP1P is designed to minimise the risk of incorrect operation and to ensure operational reliability in demanding environments.
Sockets and plugs are colour coded in accordance with IEC 60309, allowing the voltage level to be identified at a glance. This significantly reduces the risk of incorrect connection.
An integrated mechanical interlock prevents the plug from being disconnected while the circuit is live. This eliminates the risk of arcing when disconnecting under load.
The earth connection is made before the phase contacts close and broken last. This ensures continuous protection against electric shock throughout the entire connection process.
The socket can be padlocked in the open position, preventing unauthorised re-energisation. Relevant for installations with lockout/tagout procedures.
The enclosure is made of BMC fibreglass (Bulk Moulding Compound). The material is antistatic, mechanically robust and corrosion resistant under prolonged exposure to chemicals and UV radiation.
About the product designation: This series is referred to on this page as HSP1P, which corresponds to the certificate name (TÜV CY 25 ATEX 0207475 X). In HARDO's catalogue and on order codes, the two components appear as HS1PW (socket/outlet) and HP1P (plug) respectively. Contact us for the correct order code for your specific requirements.
The table below provides an overview of the available variants in the HSP1P series, with partial order codes, dimensions and key technical parameters. The order code is completed with a voltage code specified at the time of ordering: 4 = 110~130 V, 6 = 200~250 V, 5 = 380~415 V, 7 = 480~500 V, 9 = 600~690 V.
