COLE HERSEE 24812-01 Cole Hersee Solenoids & Relays HEAVY SERVICE, CONTINUOUS DUTY, SPST, 12V, 225A MAKE AND BREAK, 600A INRUSH, SILVER CONTACTS

Cole Hersee intermittent and continous solenoids provide safe, dependable control of electrical systems on all type of DC low voltage vehicles. In addition, they are ideal for marine applications and for forward and reverse systems in golf carts, garden tractors, fork lift trucks and winch operation.
Solenoids are relays which are commonly used to remotely switch a heavier current. By using a solenoid, the amount of heavy wiring needed to power the load is reduced, since the control circuit mounted inside the cab typically utilizes a smaller wire gauge.
Housing are available in plated steel, phenolic or plasticized steel. A latching solenoid can act as a remote disconnect switch.

• For use with heavy vehicles, materials handling, hydraulic systems, large DC machinery, and electric vehicles. spstSingle Pole, Single Throw. Circuitry which describes a switch. Single Pole means that this switch controls one circuit. Single Throw means that this switch has only two positions - and those are highly likely to be On and Off. normally open contactsA pair of devices that touch or come apart at the point where the switch throw makes or breaks the circuit. Silver contacts are common because of their low conductivity and low electrical resistance. Many Cole Hersee switches have silver contacts.. Insulated. 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! duty, 225A make and break, 600A inrushInrush is the maximum instantaneous input current drawn by an electrical device when first turned on. For example, incandescent light bulbs have high inrush currents until their filaments warm up and their resistance increases. Devices are designed to cope with inrush current, and knowledgeable electricians will make sure a circuit can safely handle such a surge, and match it with appropriate circuit protection. . L bracket. Large studs: 5/16"-24, two 10-32 stud coil terminals. 12V silver contact, 50k cycles. Silver contacts. Maximum operating voltageElectrical pressure, the force that causes current to flow through a conductor. Voltage must be expressed as a difference of potential between two points since it is a relational term. Connecting both voltmeter leads to the same point will show no voltage present although the voltage between that point and ground may be thousands of volts.
