FTM2

Product Features

The FTM2 series of moulded-case circuit-breakers can be equipped with:

- thermomagnetic trip units, for direct and alternating current network protection, using the physical properties of a bimetal and an electromagnet to detect the overloads and short-circuits;

- electronic trip units, for alternating current network protection. Releases with microprocessor technology obtain protection functions that make the operations extremely reliable and accurate. The power required for operating them correctly is supplied straight from the current sensors of the releases. This ensures that they trip even in single-phase conditions and on a levelwith the minimum setting.

- Small size,compact design

- With the same frame size, the circuit breakers are available wi th different breaking capacities and different rated currents.

- Widely adjustable electronic trip units

- Frames made of rigid materials of recyclable enginnering plastics,

- Modular and easy-to-fit internal accessories

- The internal accessories are extremely easy to install. No tools are required because they are simply snapped into place in the accessories compartments to the left and right of the handle.

- The trip unit allows the circuit breaker to be integrated in a communication network based on the Modbus protocal,the devices provide standard RS485 interface as the physical means for tada transmission. It allows a wide range of information to acquired and transmitted remotely.

- programming the electronic trip unit in remote mode;

- to know the state of the circuit breaker(open/closed/tripped) in remote mode.

YouTube Video Index — A list of all of my videos: http://poolmandave.blogspot.com/2014/03/swimming-pool-tips-reviews-how-to-video.html

The Intermatic Timer is the most common pool timer on the market. Here are some user guide tips and some troubleshooting for the most common problems you will have.

There are two voltage rated versions used on pool equipment. The most common is the 240 volt (208-277 volt) T104M, and 120 volt T101 Model. Most pool equipment is on a 240 volt breaker. Check your sub panel or main breaker panel to see if the timer is hooked up to a double breaker (240Volt) or a single breaker (120 volt). The timers are not interchangeable so if you need to replace yours, get the right volt/amp rating.

These timers seem to last forever. The first 3 pictured here are over 20 years old. I am surprised when one breaks down. A very well constructed product.

If you follow the tips and the timer is still not working, then you will need to swap out the Timer Mechanism. Refer to these two videos if you need to change out your non-working timer:
