TP+N
- Better Protection : Voltage protection level Up upto 1.3 kV, suitable for protection of all terminal equipments
- Both Common & Differential Mode Protection
- IEC/EN 61643-11
Pluggable Cartridges
•Faulty cartridges can be replaced without changing the entire SPD. • Cartridges can be replaced with mains voltage ON. • All cartridges are marked with characteristics for ease of maintenance.
Dedicated Protection of the Neutral
•The 1P+N and 3P+N SPDs with dedicated protection of the neutral pole discharge the common and differential mode overvoltages that may occur in installations with TT and TNS systems, when there is a voltage surge.
Remote Signaling Contact
• Option to remotely monitor the status of the surge protector. • Simplified cabling thanks to a single terminal for monitoring all poles.

Read: Contactor Sizing for 400 V and 415 V Motors: kW to Amps, AC-3 Ratings and Overload Relays →
What size contactor do I need for a 7.5 kW motor?
A 7.5 kW three-phase motor at 400 V draws about 14.5 A, so a contactor rated at least 16 to 18 A at AC-3 is the usual choice, with an overload relay set to the nameplate current.
What is the difference between AC-1 and AC-3?
AC-1 is the rating for resistive loads such as heaters; AC-3 is the rating for switching squirrel-cage motors in normal duty. Motors are always sized on the AC-3 figure, which is lower.
How many amps per kW for a three-phase motor?
At 400 V, roughly 2 A per kW for small motors, falling towards about 1.8 A per kW above 30 kW, because larger motors run at a better power factor and efficiency. Use the nameplate for the exact figure.
