  • Patent number: 8957748
    Abstract: Traditional contactors utilize a magnetic circuit that requires its coil to be continuously powered up to hold contacts together. They are heavy and bulky with the type, quality and size of materials used to develop sufficient magnetic force to hold contacts together. They are inefficient, costly and are a safety concern due to potential overheating which could result into fire or damage to connected loads. The current invention utilizes a solenoid actuator assembly with locking and unlocking mechanism in place of the yoke and armature assembly used in traditional magnetic contactors. It does not require the coil to be continuously powered up during operation and the contactor could be manually, electronically or electrically controlled thereby avoiding unnecessary power loss. They are very efficient, safe to users and connected loads, and have long service life expectancy. They are also more cost-effective and smaller in size than traditional magnetic contactors.

  • Patent number: 7817001
    Abstract: In actuating devices such as, e.g., multifunctional actuators, it is necessary in many cases to block at least one specific direction of movement. A simple and reliably operating device is proposed for this purpose, which uses an electromagnet to bring a ball from a rest position into a blocking position. In the blocking position, the ball mechanically blocks the relative movement between two parts.

  • Patent number: 7800466
    Abstract: A magnetic trip mechanism is provided for an electrical switching apparatus. The magnetic trip mechanism includes a magnetic member, an armature having opposing first and second ends and first and second sides, an armature restraint and a biasing element. The armature moves among first and second positions corresponding to separable contacts of the electrical switching apparatus being tripped open and closeable, respectively. The armature restraint includes first and second portions. In the first position, the first side of the armature engages the magnetic member. In the second position, the second side of the armature engages the second portion of the armature restraint. The armature restraint and the biasing element comprise a sub-assembly, which is removably coupled to the magnetic member. After being removably coupled to the magnetic member, the biasing element is chargeable to bias the armature away from the first position toward the second position.

  • Patent number: 7724112
    Abstract: A safety switch that includes a locking mechanism having a rod locking element that is located adjacent to a rod and engageable with the rod to lock the rod in position relative to a housing. The safety switch locking mechanism includes a locking member that is moveable relative to the housing in response to a difference in inertia between the locking member and the housing when a force is applied to the housing. The locking member is arranged to inhibit disengagement of the rod-locking element from the rod when the force is applied to the housing.

  • Patent number: 7595710
    Abstract: An electrical contact assembly includes a magnetic latch solenoid for actuating a moveable contact of a contact pair. The magnetic latch solenoid includes a magnet that latches the contact assembly in an open position, and a coil that moves an armature to the latched position under current in one polarity, and disrupts the permanent magnet field to release the armature from the latched position under current in a reverse polarity. A spring biases the contacts to the closed position. The spring is separate from the magnetic latch solenoid. The contact assembly may also include a printed circuit board for providing pulses to the coil to operate the assembly. The contact assembly is part of a remote operated circuit breaker assembly.

  • Patent number: 7570139
    Abstract: A trip actuator reset assembly for a circuit breaker includes a cradle assembly, a reset lever, a trip actuator, and a rigid element. The cradle assembly is pivotably coupled to the circuit breaker pole shaft, and includes a number of springs. A pivot pivotably couples the reset lever to the circuit breaker housing. In response to a trip condition, an actuating element of the trip actuator moves a first end of the reset lever. The rigid element is pivotably coupled to the housing proximate a second end of the reset lever. To reset the trip actuator, a guide member guides the cradle assembly into engagement with the rigid element which pivots the reset lever. The first end of the reset lever then resets the trip actuator. After reset, if the cradle assembly continues to move, then the springs accommodate the additional motion.
