SB5000 Industrial Shock-Block Manual SB5000 Datasheet   SB5060-201-0 is an Industrial Shock Block® with a supply voltage of 480 and trip level (mA) at 20 (fixed).

The 460 series is a three-phase voltage monitor that protects 190–480 V ac or 475–600 V ac, 50/60 Hz motors regardless of their size. This voltage monitor provides a user-selectable nominal voltage setpoint and will automatically sense line voltage. A...

The ALT alternating relays are used to alternate between two loads. The ALT is commonly used in duplex pumping applications to balance the runtime of both pumps. The ALT-S is used in single high-level float applications. When the float switch opens, the...

The Littelfuse models 111P (115 volt, ⅓ to 1hp); 233P-1.5 (230 volt, ⅓ to 1.5hp); and 233P (230 volt, ⅓ to 3hp) are single-phase pump monitors used in a variety of applications to protect from dry-well, dead-head, jammed impeller, rapid-cycling,...

SB5000 Industrial Shock-Block Manual SB5000 Datasheet   SB5060-001-0 is an Industrial Shock Block® with a supply voltage of 208 and trip level (mA) at 20 (fixed).

The 350 series is a heavy-duty voltage monitor. This product should be used when high-current relays or dual contacts are required or when 480 V controls are used. Since the 350 series uses heavy-duty relays, it comes in fixed-voltage range models rather...

Surge protective devices (SPDs) provide equipment protection from transient overvoltage events lasting microseconds. By limiting the overvoltage to the equipment during these events, costly damage and downtime can be mitigated. The NEMA-style SPDN series...

The SPD2 1P+0 series is a surge protection device that safeguards components from transient overvoltage or surges that last micro-seconds by limiting the fault current to a load or the unit being protected. The majority of surges are caused by equipment...
