The new Littelfuse Class H blocks offer many advantages over previous generations that are noted in the features and benefits section. Class H and Class R fuse blocks are dimensionally the same, but Class R blocks incorporate a rejection feature, which only allows Class R fuses to be inserted.

POWR-SPEED SQB ESR 1500VDC 1XL BOLT 200A

SOLID STATE TIMER

FUSE 125V ALARM FUSE BULK H-PACK 10A. Color-coded indicator flags indicate ampere rating. Body is constructed of black polyphenylene sulfide with UL-94V0 flammability rating, contacts are of bright alloy-plated beryllium copper. Ideal for telecommunications and control panel circuits.Eliminates down time by immediately pinpointing the blown (open) circuit while triggering LED or audio alarm, while placed in mating holder (482 Series). Clear plastic lens option available for additional safety.

PUMP RELAY, 16A BUILT-IN CTS, 240VAC. The PGR-6800 Pump Protection Relay provides protection for pumps with three-phase motors up to 1,000 Vac. No current transformers are required for currents up to 91 A. The protective functions include overload, phase unbalance, phase loss, phase sequence and undercurrent. The PGR-6800 Pump Protection Relay is ideally suited for applications where operating without load can induce failure. Motor current is monitored and an undercurrent trip occurs when the current drops below a preset level. No additional level detectors are required.

SE-325DN is a neutral-grounding resistor monitor with a supply voltage of 120 ac-dc and a ground-fault trip level of 0.5–4.0 A.

SE-325DSNT is a neutral-grounding resistor monitor with a supply voltage of 120 ac-dc and a ground-fault trip level of 0.5–4.0 A.

G3600 Voltage Relay. 24V DC. The G-Line relays are mainly intended for use in land-based applications. The G-Line relays provide an efficient solution for applications where flexibility and cost of purchase are the main issues. G-Line relays provide high quality, proper measuring techniques and a vast number of programmable options.

Motorized Potentiometer24VDC, 10turn,100. The E7800 Motorized Potentiometer is typically used as an interface between increase/decrease relay contacts (or push buttons) and a device requiring control by an external potentiometer (e.g. the speed trim of an electronic governor). All three wires of the potentiometer are directly accessible on external connection terminals, thus providing the best possible flexibility for almost any application. A special version of the E7800 with DC voltage output is also available. The DC output voltage follows the position of the potentiometer. The design of the E7800 ensures that the potentiometer will “remember” its position although supply is lost

Alarm Annunciator. Alarm annunciator. Compact unit for flush mounting. 8 input contacts normally open or normally closed. Time delays 50 msec. - 15 sec. individually selectable on all channels. One common output relay for sirenand two programmable output relays for alarms with voltage free contacts. LED color change through plug-in system. Plug-in terminal block for easy service. Two integrated push buttons for siren reset/lamp test and alarm accept. DC or AC supply voltage. Remote individual selectable blocking with adjustable unblocking delay 1 - 15 sec. External dimming possibilities.

SE-325S is a neutral-grounding resistor monitor with a supply voltage of 120 ac and a ground-fault trip level of 0.5–4.0 A.
