There has been close cooperation between the industry and DOD representatives to
As others have answered, the symbols are those of a relay and fuse. Figure 1. European electrical control drawing symbols. The first contact will be numbered 1x, the second 2x, etc. Normally closed will be numbered n1 - n2 (where n is the contact) and normally open will be numbered n3 - n4.

1. Introduction . A contactor is a relay which is capable of switching large electrical loads.. Contactors and relays are operated by applying a voltage to the coil of an Electro-magnet, which will cause a switch, (or several switches) to close.
This article will deal with built-in motor protection with thermal overload protection to avoid damage and breakdown of motor. The built-in protector always require an external circuit breaker while some built-in motor protection types even require an overload relay. Post a Question, Get an Answer.

The vector stencils library "Switches and relays" contains 58 symbols of electrical contacts, switches, relays, circuit breakers, selectors, connectors, disconnect devices, switching circuits, current regulators, and thermostats for electrical devices. <br>"In electrical engineering, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting ... contactors up to 32A in a 45 mm frame Finger-safe and back-of-hand proof ratings Direct PLC control on 185A–2000A contactors The XT line includes a large offering of power control components and accessories that cover a broad range of applications and ratings: Three-pole contactors to 2000A Four-pole contactors to 200A symbol standards. Because of these standards, you will be able to read all diagrams that come across your workbench. Figure 3 shows many of the most commonly used symbols on Control diagrams. On Contacts and Switches or Pushbuttons, you will ﬁnd a designation of NO or NC (Normally Open or Normally Closed).
