COLE HERSEE part description

Cole Hersee Battery Selector Switches energize either or both of two batteries.
Master disconnect switches prevent tampering of theft when equipment is unattended.
Battery isolators prevent the battery with the higher charge from draining into the battery with the lower charge.
Battery-related accessories include remote battery jumper terminals, feed-through studs, lockout lever kits and face plates.
All products listed in this section can be found in Section J of the Cole Hersee D-275 CATALOG.

Two positions: Off-On.
For 6-36V DC systems.
dpstDouble Pole, Single Throw. circuitry which describes a switch. Double Pole means that this switch controls two circuits. It's like having two switches in one switch body, except that the switching action is the same in both. Single Throw means that this switch has one On position. It's likely to be an On-Off switch - but it controls two independent circuits. Will disconnect the batteryA collection of voltaic cells grouped together to provide higher voltage and/or higher current than a single cell. The battery is a common DC power source, especially for vehicles or equipment that is used remote from the domestic power supply.
Emergency vehicles and utility vehicles often have dual battery systems because of added power demand. Such systems necessitate the use of a Battery Selector Switch or a Low Voltage Disconnect Switch. and the alternatorCommonly refers to the DC charging device on an engine. The alternator is actually a three-phase AC device producing AC which is then rectified by a diode bridge to create direct current. In selecting a Battery Isolator, it's important to match the type of isolator to the alternator. or generatorA machine with rotating parts that is capable of generating electrical power. In the narrow definition 'generator' refers to a DC machine and 'alternator' refers to an AC machine. Sometimes the term generator is used to refer to AC machines as well. fieldTypically refers to a magnetic field. Specifically used when discussing the rotating electromagnetic field associated with an alternator. By varying the field current, thus its strength, the output of the alternator may be controlled. circuit.
Electrical ratings: 125A continuousCertain switches, like solenoids can be rated for continuous or intermittent (infrequent) use. A comparably-constructed switch can generally be used with a higher current than the other switch, but with the proviso that a cooling time is allowed. There are no such restrictions on a 'continuous duty' switch. You can use a Continuous Duty Solenoid instead in place of an Intermittent Duty Solenoid, but it would have a shorter life expectancy compared to the purpose-built Intermittent Duty Solenoid. You cannot use an Intermittent Duty Solenoid in place of a Continuous Duty Solenoid!, 750A intermittent; 15secs On, 5min Off. Up to 36V DC max, carry only.
Silver contact surfaces.
Both poles are separately insulated.
Four 3/8" -24 studs. Lockwasher and two brass hexnuts per stud are provided.
3/4" -16 brass mounting stem.
Operating temperature range: -40Â° to 85Â°F ( -40Â° to 29Â°C).
O-ring seal in mounting stem; gasket seal at terminal insulator.
Epoxy seal at case, mounting stem and locating pin.
Heavy duty plated steel case.
With indexing pin.
Mounting torqueA measure of how much twisting needs to be applied to a fastener (such as a screw or a hexnut). The unit is expressed in force x length. The SI (metric) unit is newton meters (Nm); in inch measurement, pound foot (lb-ft) or pound inch (lb-in) is used. 20ft lbs (27Nm); stud torque 4.4 to 7.4 ft lbs (6-10Nm).

Cole Hersee Double Pole Master Disconnect Switch

The Cole Hersee double pole master disconnect switch can effectively cut off the battery, alternator, or generator field circuit from the electrical system. Each unit comes with terminals, lock washer, and hex nuts.

Features & Benefits

Ensures the electrical system shuts down during maintenance or in an emergency
Can control up to two systems or disconnect both positive and negative of the same circuit
Epoxy and gasket-sealed construction with both poles separately insulated
High-quality silver contact surfaces and brass hex nuts

Cole Hersee® is highly valued in the heavy duty truck industry. It is a leading manufacturer of heavy-duty battery master switches that are widely used as OE equipment by leading heavy-duty vehicle manufacturers. These switches are essential safety components for trucks as they help prevent theft, tampering, electrical fires, and battery drain. Founded in 1924, Cole Hersee is committed to improving vehicle safety by partnering with ECCO Safety Group Australia (ESGA) to establish and implement safety standards for trucks that drive onto mining sites.
