VOLTAGE RELEASE (VR) FOR TM2

 

WATERTIGHT BOX FOR TM2-E

For increasing the effectiveness of the
thermomagnetic breakers TM 2-Exx operation, they
can be supplied with auxiliary devices, designed
for widening the practice range and improving the
technical characteristics of the breakers.
The release is designed to switch off the
thermomagnetic breaker when the controlling voltage
falls under breaking level 0.55 to 0.7 UN and does not
allow switching on of the breaker unless the voltage is
over 0.85 Un.
 
FUNCTIONS:
• switching off the breaker at power supply voltage fall
under 0.55 – 0.7 Un
• does not allow switching on of the breaker when the
power supply voltage is under 0.85 Un
• prevents unwarranted secondary start of the breaker
at falling off and restoring of the power supply voltage
• protects the motor at lack/lowering of the phase
voltage
• used as a protective operating element in control
panels of induction motors
• remarkable with high reliability of current
characteristics
 
MOUNTING:
• laterally to a breaker
• At the side of the breaker through special openings

 

Specially designed plastic box with silicon screen for
increasing the IP code from dust and moisture to IP
65. Designed for thermal-magnetic circuit breakers of
up to 32A
• Mounting:
  • mounting position: vertical gradient, maximum± 5°
  • mounted to horizontal surfaces (walls) with bolts
  • the breaker TM2 Exx is fixed inside of it on rail
• Plastic: wear resistance of UV rays and
non-flammable (self-extinguishing material)
 
 
AUXILIARY CONTACT BLOCK TM2 AE11-
SIDE MOUNTING
 
It is designed to switch on operational systems
or signalization. Designed with one NO and one
NC contact. It changes the position of its contacts
according to the position of the breaker (switched on/
off) to which it is mounted.
• Mounting:
  • laterally to a breaker TM2-Exx
• Plastic: wear resistance of UV rays and nonflammable
(self-extinguishing material)
• Ambient temperature: -10°C + 65°C
• Altitude: up to 2000m
