Types used in commercial and industrial low-voltage distribution systems are rated to safely interrupt 200,000 amperes. The rating of power circuit breakers varies according to the application voltage; a circuit breaker that interrupts 50,000 amperes at 208 volts might be rated to interrupt only 10,000 amperes at 600 volts, for example.
Brake horsepower per cubic centimeter or (bhp/cc) is a figure of merit that is used to indicate the 'state of tune' of an internal combustion engine. It is defined as the ratio of the engine's net power output to its displacement, the internal size. Power is measured at its rated speed and full throttle.
Contact load in amperes for heaters (AC1) and motors (AC3) can be found directly on the contactor. The "Utilization category" are mainly categorized in IEC 60947 in the following volume: Volume 1: General requirements; Volume 2: Circuit-breakers; Volume 3: Circuit-breakers, circuit-breakers, switch-disconnectors and switch-fuse units
The engine displaced 4.5 L (4,477 cc) with a bore and stroke measuring 100 mm × 95 mm (3.94 in × 3.74 in), respectively and a 9.0:1 compression ratio; the head used Toyota's narrow-angle overhead camshafts for better fuel economy. [1] The 1FZ had only two variants available: the 1FZ-F and the 1FZ-FE.
The addition of twin turbochargers, jointly developed by Toyota with Hitachi, in sequential configuration had raised its commercially cited output from 230 PS (169 kW; 227 hp) to the contemporary industry maximum of [convert: invalid number] at 5800 rpm. In its first appearance, torque was advertised as 44.3 kg⋅m (320 lb⋅ft; 434 N⋅m) at ...
The 1KZ-T is a version of the KZ series engine that used a fully mechanical injector pump instead, 3.0 L (2,982 cc), 4 cylinders, SOHC, 2 valve per cylinder turbo diesel engine. Compression ratio remains the same at 21.2:1. Maximum output is 123 hp (92 kW; 125 PS) at 3600 rpm and maximum torque is 296 N⋅m (218 lb⋅ft) at 2000 rpm. [1]
Other manufacturers may modify the engine after it has left the Toyota factory but the engine still keeps the original Toyota designation. For example, Lotus added a supercharger to the 2ZZ-GE in some versions of the Lotus Elise and Exige, but the engine is still labelled 2ZZ-GE, not 2ZZ-GZE. Examples: 3S-GTE 3S – Third model in the S engine ...
For example, a 100 HP, 460 V, 60 Hz, 1775 RPM (4-pole) induction motor supplied with 460 V, 75 Hz (6.134 V/Hz), would be limited to 60/75 = 80% torque at 125% speed (2218.75 RPM) = 100% power. [26] At higher speeds, the induction motor torque has to be limited further due to the lowering of the breakaway torque [ a ] of the motor.
