How to Properly Protect a BESS Power Circuit from Overcurrents
Overcurrents can cause extensive damage in a battery energy storage system as well as costly downtime. That is why circuit protection is imperative. Circuit protection fuses have many advantages including easy installation and replacement, low watt loss and a compact size. But, sizing fuses accurately is challenging. Littelfuse provides the
formulas to calculate fuse sizes for maximum protection, reliability and cost-effectiveness.

Prevent Electrical Shock In Commercial and Industrial Applications
Shock Block stops the problem before it happens by interrupting circuit faults before shock occurs instead of simply mitigating electrical shock.
Shock Block is the most comprehensive UL 943C listed GFCI on the market. Other workaround product combinations are inadequate when it comes to meeting code requirements or, more importantly, protecting human life.

Littelfuse SPD2 Series of Type 2 Surge Protection Devices
Littelfuse SPD2 Series Type 2 Surge Protection Devices (SPDs) for branch
circuits safeguard components from transient overvoltage or power
surges by limiting the fault current to a load or the unit being
protected. They are designed to prevent equipment damage or downtime
caused by these power fluctuations.
