The SPBT12 device provides protection against transient overvoltage caused by direct lighting strokes for lighting protection levels III and IV acc. to IEC 62305.

Usually when an external lightning protection system is installed, an internal lightning protection system is also required for which the type 1/2 combination offers the best solution.

Power Entry Modules with Integrated Circuit Breakers

Systematically reducing components is a major success factor for a cost-saving design. And what is more: Fewer components increase the overall reliability and usually lead to space-savings.

E-T-A’s power entry modules combine up to five functions in a single component: a C14/C20 appliance inlet, resettable overcurrent protection, an ON/OFF switch, a line filter and an optional undervoltage release, remote trip or auxiliary switch.

Compared to standard connector modules with fuses the E-T-A power entry modules are equipped with resettable circuit breakers. After an overcurrent trip they can be reset quickly, reliably and easily. Time-consuming fuse replacement is eliminated. Thanks to screw mounting, E-T-A power entry modules have a firm and robust fit in the housing and can thus withstand even high pull-out forces of power cables without any problems.

Benefits:

• Reduced assembly and wiring effort (up to 90 %!)
• Reduced material planning and stock keeping costs
• Increased equipment uptime: Quickly and easily reset circuit breakers
• Time-consuming fuse replacement is omitted
• Low operational costs: No expenses for procurement, inventory management and service for fuses
• High safety: multipole circuit breakers reliably interrupt the current-carrying phase conductor in the event of a fault. This prevents electric shocks.
