An apparatus comprising: a motor overload enclosure; and two or more motor overloads configured to protect two or more motors, each motor overload of the two or more motor overloads being located within the motor overload enclosure, each of the two or more motor overloads being external to an enclosure housing a motor of the two or more motors, each motor overload comprising one or more current sensors (202; 402), each current sensor comprising a conductor, the conductor arranged to provide power to a motor - "protected motor" - protected by the motor overload; and a motor trip module (204; 302) for stopping current flow to the protected motor in response to determining that a thermal state of the protected motor has reached a thermal limit, wherein determining that the protected motor has reached a thermal limit comprises using a current signal from at least one current sensor of the one or more current sensors (202; 402) that senses current of the protected motor to determine a thermal state of the protected motor; characterized in that each current sensor comprising a magnetic core and said conductor being positioned within the magnetic core, and the apparatus comprises a single motor controller configured to control the two or more motors, wherein each output conductor of the motor controller is divided into corresponding conductors providing power to a protected motor to feed each of the two or more motors. a motor overload enclosure; and two or more motor overloads configured to protect two or more motors, each motor overload of the two or more motor overloads being located within the motor overload enclosure, each of the two or more motor overloads being external to an enclosure housing a motor of the two or more motors, each motor overload comprising one or more current sensors (202; 402), each current sensor comprising a conductor, the conductor arranged to provide power to a motor - "protected motor" - protected by the motor overload; and a motor trip module (204; 302) for stopping current flow to the protected motor in response to determining that a thermal state of the protected motor has reached a thermal limit, wherein determining that the protected motor has reached a thermal limit comprises using a current signal from at least one current sensor of the one or more current sensors (202; 402) that senses current of the protected motor to determine a thermal state of the protected motor; one or more current sensors (202; 402), each current sensor comprising a conductor, the conductor arranged to provide power to a motor - "protected motor" - protected by the motor overload; and a motor trip module (204; 302) for stopping current flow to the protected motor in response to determining that a thermal state of the protected motor has reached a thermal limit, wherein determining that the protected motor has reached a thermal limit comprises using a current signal from at least one current sensor of the one or more current sensors (202; 402) that senses current of the protected motor to determine a thermal state of the protected motor; characterized in that each current sensor comprising a magnetic core and said conductor being positioned within the magnetic core, and the apparatus comprises a single motor controller configured to control the two or more motors, wherein each output conductor of the motor controller is divided into corresponding conductors providing power to a protected motor to feed each of the two or more motors.
