Fuse Holders

The plug-in surge arresters SPPVT2 and SPPVT12 are developed especially for photovoltaic applications. They protect the installations against transient overvoltages that can be induced by direct or indirect lightning strikes.

SPPVT12: Homes with rooftop solar PV installations represent an additional vulnerability that requires surge protection. Usually this requires Type 1/2 combinations, for DC protection - based on whether the building has also a requirement for an external lightning protection system. SPPVT12 is developed especially for photovoltaic applications and protects the installations against transient overvoltages induced by direct lightning strikes.

SPPVT2: Type 2 PV surge protection is required, when there is no risk for direct lightning strikes but indirect surges can occur. SPPVT2 protects the inverter and installations against transient overvoltage due to switching and indirect lightning strikes.

These surge arresters are suitable for a wide range of surge protection in a large number of systems.

Timer relays are especially suitable for the use in passenger cars, trucks, buses as well as construction machinery and emergency vehicles. They control pumps, valves or motors, which are meant to overtravel or stay open for a defined period of time. They equally control the co-ordinated, sequential switch-on of loads to avoid load peaks (e.g. with fans).

E-T-A timer relays are available for DC 12 V and DC 24 V applications and are suitable for standard automotive relay sockets to ISO 7588.

Key Features:

• Functions: Provide ON delay, OFF delay, and interval timing, allowing for flexible, programmable operation.

• Installation: Designed to fit standard automotive relay sockets to ISO 7588, facilitating easy replacement.

Key Benefits:

• Load Management: Enables sequential switching to avoid power peaks and protects batteries.
• Durability: Engineered for harsh conditions with robust construction.
• Customization: Offers flexible, programmable parameters for specific vehicle needs.

Applications:

• Buses
• Trucks
• Construction Machinery
• Specialized Vehicles
• Protecting Circuits and Controlling Devices that need to run for a specific duration
